I guess what i would like to see is an option in settings where you can chose that tactical mode, i don't think it should be that difficult.
You should try Project Reality (a mod for Battlefield 2), and quite likely you're a perfect match for Squad which is still being developed. Check out the numerous vids on
Bluedrake42's youtube channel. I barely bother with cable TV now, just have his PR vids playing instead, though he covers numerous other games, and have a look at his recent Squad updates too.
Oh, I think you'l like his coverage of Tactical Battlefield aswell, though as a viewing experience I still prefer the PR uploads atm.
All the above are tactical based on what you said and for numerous other reasons (that's their main focus), ie. one can't just recover from injury without help; medics are vital to the gameplay, though the games vary in how the functionality operates, eg. in T.B. one can move an injured soldier away from the combat area so they can be treated elsewhere (can't do that in PR I think, though it's an older engine now).
Much as I like games like Crysis, I think if I had oodles of spare time I'd be playing PR or T.B. instead, and certainly eagerly anticipating Squad. Check bluedrake42.com, realitymod.com and other sites for more info. If you like playing tactical squad-based large pvp games, there are plenty of great options available atm that are less well known but better than the big names IMO. I think you'd particularly like PR as a starting point.
